Davemc, I too have the same problem with a 37-116. I have gone all through it, replacing caps and out of tolerance resistors, changed tubes, aligned it a few times and double checked all coils in the front end. It plays good but I am disappointed in its reception. I have a 41-250 that will run rings around the  37. The 41-250 has 2 IF stages but no RF but yet out performs the 37-116 that has an RF and 2 IF. One difference is the 37 is a long wire antenna and the 41 uses a built in loop. I plan on restoring my 620 next  to compare it's reception using a long wire antenna.
